Hi all, I installed a turbodumb (sorry smart) bleed valve on my brothers gtst r32. It all seemed to be easy enough, only one hose running off wastegate going to turbo, stuck the bleed valve in and went off to testing. Here's where the problems start :) Before the bleed valve with full exhaust/pod the car was running around 10psi. At first I had the turbosmart valve turned right down, went for a drive, still was running 10psi...the short story is that no matter how many times I turned the bleed valve to increase boost it was still the same, 10psi.

So I thought I might have it on the wrong way, no checked that, definately the right way. Then I thought maybe a wastegate problem, so I disconnected the hose from the wastegate went for a quick run, and without flooring it completely, sure enough the guage went up to around 13-14psi. So I thought, good not a wastegate problem, must be the controller. To make sure it was 100% the controller, I took it off and stuck it on my car (180sx) I again wound it back to the lowest setting and went for a drive in my car...and lo and behold I only boosted to about 7-8psi (which is what it should do at fully closed)

So now I'm completely out of ideas, the controller is obviously working, the wastegate seems to be working, and I'm pretty sure it's all setup correctly, afterall there is only one hose from the wastegate as far as I can tell, any ideas would be much appreciated as I'm quite confused, thanks.

i had a dual stage turbosmart controller that i hooked up myself.

It didnt seem to let me run any less than 1bar of boost.

I swaped it for an old school single stage turbosmart one and it works fine.

The dual stage worked fine on my mates wrx too.

So it could just be that the controller you are using doesnt work on YOUR car??

I also put a turbosmart T piece on my rb20det in my s13. It kept trying to climb all the way to 1bar on whichever setting i put it on. I was then told that you need a restrictor in the line to slow down the pressure hitting the bleed valve so it can handle the sudden boost. We tried another T piece turbosmart one and it did the same thing. I just took the bleed valve off as i didn't want to deal with running high boost without a fmic.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
